Ventair Higroster

Proven solution in a compact design. The heart of the device is a removable hygrometer, which controls the flow according to the air humidity.

Responds to your needs

The controller mechanism is based on a small, precise device which measures relative humidity in the room and directly adjusts the air flow while adapting the ventilation performance to the humidity level.

Ventair Higroster is the first and the only trickle vent with humidity control and an aluminium body. The unique design and the materials used not only make it possible to detach the hygrometer but also ensure additional stabilization of the flow rate. The possibility of detaching the hygrometer protects the mechanism against damage during the installation of the trickle vent and window cleaning
